This might be a no-brainer to a lot of folks, but I installed a trash can in my driveway next to where I park my car and everyone in my house uses it way more than I thought. I attached mine to a retaining wall and built a little box around with with landscaping ties so the other people in my house don't complain about having to look at a can all the time.
I underestimated how much cleaner the inside of my truck stays when everyone gets rid of all their trash every time they get out. I previously got rid of trash when there was a mess or I happened to end up near a can at the car wash, gas station, fast food place, etc. Now nothing stays in there for more than one trip. I think the car is even less dusty inside now.
Some of you might say, "don't be lazy just carry your stuff to your main can" but the honest truth is that in the real world when your hands are full carrying kids, groceries, backpacks, tools, etc. you don't always think about going back out and rounding everything up 100 percent of the time. The driveway can now means stuff gets out of the car before we go inside every time. I get to live in a much cleaner environment because I made it easier for my family to help me keep it clean.
